Specification of Letters Patent.

Patented June 23, 1908.

Application filed December 26, 1907. Serial No. 408,017.

T 0 all whom it may concern:

Be it known that 1, AUGUST SOHIEPE, a citizen of the Empire of Germany,residing in Charlottenburg, near Berlin, in said Empire, have inventedcertain new and useful Improvements in Type-Casting Machines, of whichthe following is a specification,

The object of this invention is to provide a new or improved castingmachine preferably for the manufacture of single printing type, in whichthe casting molds are arranged in groups in the usual way upon acarrier, for example on the periphery of a revolving drum, and are thensuccessively brought in front of the casting mouth of a melting pot byintermittently moving the carrier drum. After the fluid metal has beenforced into the molds under the action of a casting pump, the moldcarrier, for example the drum is moved through an angle of say 90, afterwhich the cast printing type are freed from the runner connecting theirfeet and are then, on a further rotation of the mold carrier through anangle of say 90, ejected from the molds and automatically conveyed intothe channels of a suitable type magazine.

There is shown in the accompanying drawing a portion of a constructionof type casting machine embodying this invention and in which the typemolds of one font are arranged in four casting sections on the peripheryof a wheel or drum which is rotated intermittently, each movement beingthrough an angle of 90.

The type molds successively pass in front of the casting hopper of anordinary melting apparatus, in which position they are forced full ofmetal by the action of an ordinary casting pump. In the succeedingpositions of the intermittently rotated wheel the type are freed'fromtheir runners, automatically ejected from the casting sections andconveyed into the channels of the type maga- Z1118.

The channels of the type magazine correspond in their arrangement andnumber to the several groups of casting molds.

Figure 1 shows partly in section and partly in elevation one castingsection and the type magazine with the operating devices for the variousmovements. Figs. 2 and 2 are front-views of the parts seen in Fig. 1 butwithout the magazine; Fig. 3 is a detail view hereinafter referred to.

In this class of machine the molds for the bodies of the type areconstructed in a similar way to that shown in Fig. 2 of the accompanyingdrawings from which it will be seen that small plates 6 serve as sideboundaries and the faces of other. small plates (1 as lower boundariesof the mold, the whole casting mold being covered in at the top by acommon cover. Now great difficultyv obtains in so fixing the cover thatit shuts off the several casting molds in an absolutely liquid tightmanner from each other, as for such purpose it must be in contact withthe faces of all the small plates 6. The result is that there is alwaystrouble with the fluid metal overflowing at the top whereby the severaltypes are caused to stick together. or similar troubles arise. In theimproved machine this disadvantage is obviated by forming the upperboundary surfaces of the several molds of a number of small plates 0which accurately correspond in thickness to the bottom plates (Z.

The molds for the bodies of the types are therefore formed by threedifferently shaped small plates 0, d, and e which are held, preferablyindove-tail grooves c and d, in the casting section b. The small plates 0,d and e may however be secured in other ways, for example by flatgrooves or the like, but the mounting must be very exact and so that thesmall plates can move sidewise in their grooves but not upwardly ordownwardly or forwardly or backwardly.

The matrix plate 0 bears against the back of the small plates 0, d, c.This matrix plate consists of a strip of metal into which are sunk themolds for the heads of the type. The matrix plate 0 may be adjustablysecured to the casting section b by adjusting screws 0 and correspondingclamping screws, or in any other similar manner.

Each casting section comprises cross bars n, n M, n which are securedtogether by screws 0 To enable type of different sizes to be cast in onemachine the small plates (Z and e are carried in the bar n which can beadjusted vertically in a dove-tail or similar groove and secured afteradjustment by means of clamping and tension screws g. This.adjustability may however be effected in other ways say for example bymaking the whole lower part of the casting section adjustable.

The upper part n is so mounted that it can be pushed out in thedirection of the arrow Fig.1. In this upper part thesmall plates 0 arelikewise so secured in a dove-tail or similar groove that they can movesidewise but not upwardly or downwardly or backwardly or forwardly.

At their rear ends the small plates 0 are each prolonged at p and belowthis prolongae tion formed with a nose 8. The nose s gives the cast typea small nick, the signature so called, near its lower end in thevicinity of the foot. Several such noses may be pro vided on each topplate 0 arranged say behind each other so as to give to the type whencast a number of nicks, or signatures. This is for the purpose of moreexactly guiding the type bodies when sliding out.

When the upper part n is moved in the direction of the arrow the casttype will be ejected from the section by the noses s. The upper part nmoves so far outwardly that the entire type is brought out of the reachof the plates 0, d, 6 only the projection p being still between theplates 6 and by this means insuring the plates. 0 being smoothly guidedback into position between the side boundary plates 6.

The upper part a is caused to slide back by mechanism shown in Figs. 1and 2 in the following Way:On each end of the part n of the castingsection is fixed a guide pin 15 which of course moves with the castingsection in a circular arc. Upon a shaft u is mounted a U-shaped lever 12the thickened upper part of which is formed with guide grooves w. Thelever q) is given a pendulumlike movement, through a roller cam ac whichis fixed upon the driving shaft, or in any other similar manner.

l/Vhen the pins t are situated in the guide grooves w the lever 12 makesa movement to and fro once and thereby pulls the upper part n once inand out.

When the upper part n moves outward the type are carried with it andimmediately thrust into the channels of the magazine. These channelsaccord in their arrangement exactly with the several castinginstruments, as hereinafter described.

As now the freshly cast type frequently adhere to the upper plates 0 andwould be consequently carried back again into the casting section orgive rise to other troubles some appliance must be provided which willknock off the type at the proper moment. Figs. 1 and 2 show oneconstructional form of the knocking o'lf appliance but the knocke ingoff may be effected in any other appropriate manner. Upon the shaft uand be-, tween the members of the forked arm of the lever 'Z) is mounteda double lever y, the lower end y of which is recessed to removablyembrace the lever 1). One arm of a bell crank lever z engages the upperend of the lever 'y. The bell crank lever z is pivotally mounted at .2and operates a slide 1. hen the lever 12 is moved the smaller doublelever y is likewise caused to move and, by means of the bell crank leverz to move the slide 1 upwardly or downwardly. To the slide 1 is attacheda knocking off tongue 2 which firmly holds the withdrawn cast bodies onthe rearward movement of the part n and they then pass into themagazine. A spring 3 brings the lever y back into its normal positionafter the conclusion of this operation. In order to prevent the castingsections from striking against the knocking off tongue 2 during thefurther movement of the former, arms 4 are fixed to the slide 1 which,during the angular movement of the casting sections, are forced back bythe next following casting section and consequently moves the knockingoff tongue 2 out of the range of the rotating casting drum. Thisoperation is repeated in like manner on each rotation of the drumthrough an angle of 90.

In order that the knocking off appliance shall work properly it isnecessary to stop the casting drum exactly at the proper time; aconstructional example of an appliance for this purpose is shown in Fig.3. 5 is a lever that is moved from the driving shaft by a suitable cam6. It is pivoted at 7 and its upper end carries a bolt 8 which at theproper moment engages periodically in each of the four holes of anarresting disk 9 and releases it again also at the. proper moment, afterwhich the arresting disk is again permitted to rotate through an angleof 90.

It has been found in practice that in the working of such castingmachines the plates 0, d and 6 must be very tightly pressed together atthe moment of casting so as to prevent any metal flowing between them oroverflowing from the molds formed by the plates which prevention isnecessary in order to obtain sharp edged type bodies. For this purpose,accordin to this invention there is provided an app iance of very simpleconstruction and the action of which is certain. On each side of thecasting section is arranged a pressure lever f, Figs. 1 and 2, which ispivoted at g by means of a screw threaded bolt h which has preferably ascrew thread of rapid pitch. Projecting from the lever v in the path ofthe casting section, at suitable points such as i, are pins 70 which, atthe proper moment, come into contact with the pressure leversf androtate them to a cer tain extent and then leave them again by passingthrough a groove 1 formed therein. This rotation of the lever f andconsequently also that of the screw threaded bolt h presses the plates0, (Z and e still more closely together than they were already pressedtogether by the hand adjusted set screws m. This operation is repeatedat each partial rotation of the drum a through an angle of 90.

Before the ty e bodies enter the magazine the runners SM 1 adheringthereto are removed by a suitable appliance shown in Fig. 2. Thisappliance consists of a cutter disk 10 which is rotated through suitablegearing 11 and is moved to and fro by a series of rods 12. Grooves 13 orthe like guide the cutting appliance in the frame of the machine. Tworollers 14 adapted to run over the face of the casting'section carry theappliance and so guide it as to insure that the same amount is alwayscut away. The cutting arrangement is regulated by an adjustable screwthreaded bolt 16 having threaded on it a spring 17 which constantlytends to force the running rollers downwardly.

A further improvement, that facilitates the proper working of themachine is the provision of a device for previously heating up theseveral casting sections; such device consists for example of a gaspipe18 as shown in Figsl and 2.

Upon the casting machine is also provided a movable magazine bridgeadapted to receive in four channels formed by separate rulers, the ty ewhen finished and ejected from the mac 11116 by the ejecting appliancehereinbefore described. The swinging maga zine bridge is driven by afour stepped cam or the like 19 keyed upon the drum shaft 20. The entiremagazine 25 is carried by a standard 23 in a bearing 26. Upon thestandard 23 is pivoted one end of a lever arm 21 whose other end carriesa lateral pin 22 on which is mounted to rotate a roller that works uponthe cam 19. The cam is intermittently rotated through an angle of 90 Asthe cam 19 is constructed as a four step cam the lever arm 21 will bemoved into four different positions which will be transmitted to theswinging magazine bridge 25 by the link 24. The steps of the cam 19correspond in their distances from the center exactly to the distancesapart of the several compartments of the magazine thereby insuring thatthe casting section provided with finished printing type comes in linewith a corresponding compartment of the magazine at every partialrotation through an angle of 90 of the cam. The finished printing typeare therefore ejected out of the casting section by the ap- ,pliancealready described and pass into the channels of the magazine bridgeformed by rulers, where one type ranges itself against the other andpushes it further on, as well understood.
